#1 Eibach does not list an ix specific spring, yet I know several members have used them. For those that are running Eibach's on E92 ix - are you using the 328i Coupe #2091.140, 328i Sedan #2085.140 or 328i Vert #2099.140 (which I found some vendors list as correct for 328ix Coupe also)?

#2 From member reviews, I gather the H&R springs offer bigger drop-but the ride is harsher, while Eibach's are less drop with comfortable ride. Is this the consensus?

I never intend to track the car - just normal every day driving. Roads here in Western PA are definitely not the best, but the non-RFT tires should soak up some of the shock over the RFT's.

Would you recommend H&R/Bilstein, Eibach/Bilstein for my application & why (if you have direct experience)...

OK, well I never went that far because I would never buy directly thru them - you are correct, only the rears come up.

Which is even stranger because I have found other online vendors selling Koni sets listed specifically for the 328ix that include all (4) shocks and even list the part numbers for the fronts the same as numbers on Koni site.

Wonder what they give you then if they aren't available-sounds like some fraud going on there...

That's crazy, why go to all the trouble of making part numbers & listing them for an app if they don't actually have them? Are they something that is in process?

At any rate, I'm not going to run lowering springs on factory shocks, so I guess that changes the scope of my question/poll slightly - edited thread.

Nah, if they don't have them now they'll never have them. I'm running H&R Sports on stock shocks and, to be honest, the ride is pretty good. Obviously harsher than stock but well within tolerance. If you're considering shocks, I would recommend springing for them. Suspension installs are pricey and you don't want to have to do it twice.

The sticky at the top of the XI section has allthe info you can choke down on suspensions for the X drive cars. Turner is running a sale of 10% off for the month of March on Bilsteins...mine will be shipping soon and will be matched to a set of Eibachs. I probably would have used Koni but as has been discussed ad nauseum on these boards, there are no Konis for the front of the 335 X drive cars, nor will Koni ever build one, so it seems.

I am thinking about lowering, and if I do I am 90% sure to go the bilstein/H&R route.
It makes sense to me, the components are designed for the xdrive system, although it seems it wont get rid of the rake. But I'm going more for the tighter feel of the car than the look.

Plus they are on sale: can you say win?

Also, I'm still unsure because I want to keep my style 284 wheels (with ps2's) and am hoping it won't look cheesy... But I digress lol

OK, I get the deal with the Koni's. So since I won't run factory shocks with lowering springs, my only option is the bilsteins.

Still doesn't answer my question #1 as to what Eibach springs xi drivers are using?

I realize the rears are the same between i & xi but fronts are different.

So Ollie, did you just buy the i Pro Kit for your 335 since they don't list a xi kit?

The sticky is very general regarding the Eibach springs - it states Pro Kit - OK, that's great-what P/N? They don't make one for xi - so I'm looking for what xi owners went with & their impressions/experience as to how they worked...

Guess I'm leaning toward the Eibachs because the amount of lowering is not as great as the H&R's & seems peole state the ride is 'gentler' on crappy roads - but I hesitate to buy any part that is not made specifically for my application without hearing actual results.

Many people are using the Eibach Pro-Kit for 335i (not xi) without any problems. The part number is 2092.140

To be safe I guess 328ix E92 should go with 328i E92 springs - I wonder what would happen/what would be drop if 328i E90 springs were used on 328ix E92?

I PMed phrozenstone who had the Eibach/Bilstein setup before and he confirmed he used 328i E92 --> #2091.140 Front 1.0/Rear 0.8 for his 328xi E92. That is what I will be ordering. Thanks to him for clearing this up.
